@Z @chem it muy concern:

tloiown that I, RICHARD H. izen of the United States, and resident of Seattle, King county, Washington, have invented certain nevvand useful Im rovea ine is in @il-Burners, of which the ollow-v n r is a specication.

ry invention relates to improvementsin oil burners and comprises certain novel and combinations of parts which will bv hereinafter described and particularly poiiitefl out in the claims. l

he object of my invention is to simplify and improve the construct-ion of devices ot s this character' to make them cheaper, more ig and reliable in use, and to make them more ellicient.

ln the accompanying drawings I have shown iny invention in the forms of coni struction which are now preferred by me.

ion of a4 slightly modified type of con- Ahe burner as herein illustrated, is designed particularlyy for insertion Within stoves employed for domestic purposes.

1' Such stoves inay consist of a kitchen range,

in which case two orniore burners may be ei ployed, or a heating stove, in which oase, oi inarily, a single burner would be suilicient.

in Figs. 2 and 3 I have shown a construction alf'G, which is intended as a conventional representation of a grate, as for instance, f1 grate employed Within a kitchen i range. yThe construction of this grate. is immaterial, as it is' merely employedk as a ineens for supporting the burner. Upon this grate I prefer to place a layer of material' which will close all the draft openings in the grate, except such as Will coperate withk the dralftopenings in the burner. For

' this purpose I have shown a sheet I-I of asbestes 1 or equivalent material, which is placed on top of the grate. As a substitute therefor it is evident that a sheet of metal,

or a layer of re cla may befemployed.

For purposes of escription' the burner Specification of Letters atezit. Application filed November 26, 1913. Serial No.

may' be divided into three sections or parts, Corner,`

alovver part or hase section l0, an annular or tubular upper section l2 Which may be` called the head of the burner, and connecting and supporting posts il. This constructionrsupports the upper section 12 \at such a distance above the base as to provide openings 13 between the two which cX-v tend entirely about the burner, escept as interrupted by the posts li.

The basel() is provided vvith `a primaryv i oil receiving chamber I4, with which connects an oil supply pipe l5, which pipe eX- tends downward through the grate. The oil supply to the burner first enters .the

chamber le, which chamber is closed except for its connection with the oil supply pipe and With the passages in which the oil is gasilied by the heat ofy the burner.

The oil passages referred to extend, one through each post ll and thence, by a circuitous route within the walls of the upper annular or tubular section l2. to the top thereof. The main body of the burner is composed. o' cast iron, While the Walls of i the passage referred to and the formation of the channel of the desired shape in said upper portion oi the burner, is secured by bending a piece' of Wrought metal tubing into the mold, and then/casting the body of the burner about the saine,

A piece of tubing bent to the shape oon-l i i templated by the accompanying drawings is shown in Fig'. l', and the outline of the cast portion' oithe' burner is shown in dotted\ lines. This tubing has a short section 2O at each end which is left straight, said ends extending ve Ltically in the completed. burner and being substantially parallel. -These end sections lie Withinthe body of the posts 11 in the completed burner and connect with the chamber le in the base section of the burner. Above this point the tube is bent into the form of a helix, forming coils 2l Which lie within the walls of the tubular upper section l2 or the burner. The central 'portion 22 of the tube which connects the upper coil parts, extends across the upper end of the tubular section l2 ofthe burner, preferably as a lovv arch, as is clearly shown in the drawings, and is provided vvitlia discharge orifice 23, located over'tlre'bore of the section 12. This orilice discharges the gas which has been produced from the oil 85 into the desired shape, placing this tubing 1 in passing through the passages just described, directly downward into the bore 16.

The base section of the burner, in the form of construction preferred by me, has its upper surface somewhat concave or hollowed, so as to form a cup 4Sor the reception ot a sufiicient amount of oil, which may be discharged therein and burned in order to heat the burner up to such a temperature as will properly gasify the oil, thisbeing done only at the time of lighting the burner. This maybe done by depressing the diaphragm which forms the roof of the chamber 14, as

is shown by the depression 17, or bylower-4 ing this diaphragm so as to leave a low flange or wall 18,extending about its periphery, or by doing both. This flange forms a priming cup of ample capacity for enough oil to thoroughly heat up the head or top section 12 of the burner. By forming the burner so as to locate the priming cup between the base section 10 and the volatiliting head 12, it ma be kept of sutiiciently small height that tiere will be room for it in the re pot of the ordinary stove.

The base section 10 of the burner, is provided with bosses or ears, located at opposite sides thereof and containing air con veying passages. One of these, 3, isv located just without the outline of the tubular section 12, and extends upward to a level substantially conforming to that of the side opening 13. Care should be taken to pro vide a suitable connecting opening extend ing through the grate and the layer H which is placed thereon so that lit may be freely i.

supplied with air. Outside of this, but preferably in the same lateral plane, the boss 30 is provided with a similar opening, which serves as asupporting socket for a pipe 31, which extends upward and has its upper end bent and extending over the top, of the burner, discharging its air supply into the bore of said tubular sect-ion, where it meets the gas discharged from the orifice 23.

ln Fig. 4l l have shown a construction in which a distinct and separable base memberv is employed. This base member 32 is prof vided with a cup-shaped depression 33, into which kthe base of the main body of' the burner enters. This depression 33 forms-a .supplementary receiver for the oil used to preliminar-ily heat the burner, in case an unusual amount chances to be discharged. It is not intended that this should ordinarily be filled when starting the burner, as the j cup formed bv the flange 18 is ample in size and the annular head or tube 12 has ample volatilizing capacity. lt is a safety cup intended to catch any overfiow from the regular priming cup.

The base32 carries the bosses 3 and 30, with their air conveying passages, instead of having, the latter made as an integral part of the main body of the burner. The

and base, where it meets the air being `to patent is; y

1. An oil burner for stoves comprising an construction of the form shown in Fig. 4 is otherwise such as has been described.

The iron which is cast about the pipe 2, 1s

used for two purposes. First, it constitutes a protective covering for said pipe, preventing it from being burned out by the heat of the fiame, and second, 1t forms a heat storage reservoir `which will better insure a sufciently high temperature to gasify the oil to carry over times when the flame may, be turned' low.

This form of construction also serves 'a useful purpose in this way; to form passages of such character as are desired, Within such a body of metal' by an ordinary core, would be ,very difiicult and expensive. In addition, the walls of passages so formed would. be rough and would be coated with sand and the material of which the core `was formed, and particles of this would be liable to dislodgment and to b e carried up to the orifice 23, vwhich might become thereby choked. By forming the walls of this passage ofatube about whichA the iron is cast,"

a smooth surfaced wall, free of any removable particles is, obtained.

l/Vhen in use the gas discharged from the orifice 23 is thrown forcibly downward into the central bore 16. Being mingled with the air coming through the pipe 31z this bore is filled with flame, which issues through the openings 13 between the ticxnp troduced through the passages 3, which assists 1n completing the combustion.

What l claim as my invention and deslre integral casting having a base section containing therein a VAprimary fuel receiving chamber and having a marginal upper liange forming a priming cup, said casting having an upper tubular section which is joined to the base by posts whichv are integral with each section and maintain said upper and lower sections somewhat separated, said upper section having oil 'How channels in its wall each extending through its respective post tocommunication with the primary fuel receiving chamber of the base and at its u pcd end with the upper end face of the said upper section, and a tube connecting said channel ends and extending across the centraly chamber ofthe Aupper tubular section and having au axially placed hole discharging downward. l

2. An oil burner .for stoves comprising a base section having a primary oil receiving chamber and ears at opposite sides each provided with air conducting channels extendingbetween its un( `r and its upper surfaces, and other like channels` adapted to 'form sockets for yair conveyingpipes-,Ta tubular upper sectionv i'ntnigrally connected with and supported abovedthe base by posts,
